Excerpt from Studies on the Germ Cells of Aphids My previous report on the germ cells of aphids was based on a study of the parthenogenetic and winter eggs of Aphis rosae, the brown rose aphid, and of the spermatogenesis of Aphis oenotherae, found on the inflorescence of Oenothera biennis. During the past summer and autumn material from more than twenty species has been collected and examined. In some cases it has been possible to study all of the forms of one species, in other cases only the parthenogenetic eggs, only the winter eggs, or only the spermatogenesis. It has become evident in the course of the work that little dependence is to be placed on the present classification of aphids, and that a reclassification based on the cytology of the germ cells may be necessary. For example, it appears that at least three distinct species are usually included under the name Aphis rosae. No attempt will, therefore, be made in this paper to give the Latin names of the species studied, but they will be designated by the names of their host plants, and identified by brief description where it seems necessary. This comparative study was undertaken in the hope of throwing more light on the question of sex determination, and the descriptive part of the paper will be followed by a further discussion of the bearing of the facts recorded on that problem. Methods. The methods used were for the most part the same as in the previous work fixation with Gilson's "acetic alcohol with sublimate" (Lee, sixth edition, p. 65) and staining by Heidenhain's iron-haematoxylin method. Some material was fixed in Flemming's fluid, Hermann's platino aceto-osmic, and Gilson's mercuro-nitric, but such fixation brought out no new points in structure, and was, in general, less satisfactory than fixation with Gilson's acetic alcohol-sublimate formula.
